The Four Chaplains, also sometimes referred to as the "Immortal Chaplains" or the "Dorchester Chaplains", were four United States Army chaplains who gave their lives to save other civilian and military personnel as the troop ship sank on February 3, 1943, during World War II. They helped other soldiers board lifeboats and gave up their own life jackets when the supply ran out. The chaplains joined arms, said prayers, and sang hymns as they went down with the ship.
